While I don't doubt that GoDaddy and other inexpensive shared hosting providers aren't the best environment for MODx (or really even "good" as web hosts go), it still baffles me that this particular site has these troubles. It's also a bit frustrating that the party line on this issue always seems to be "shared hosting is the problem" right out of the gate. I was hoping that through providing in depth information about my particular case, perhaps I could help shed some light on this. As detailed above, I've tried every "fix" for bug #3111 (or #7324) including the use_flock fix and am still experiencing issues.
The one thing I've noticed is there are 8 files sitting in the directory core/cache/resource/web/resources/1/ and when I view them, they all look like they contain information for the home page, which is resource 1. There are files that reside in that one's parent directory (core/cache/resource/web/resources/) with names like 8.cache.php, and I do NOT see a file named 1.cache.php. Since I have my home page (resource 1) set to uncacheable, I don't expect to see a file here. But what are the files in the /1/ directory? And all these directories seem to have the correct permissions (705).
Also, I'm working through the error logs from the past few days. Just needed to look a little harder for them, it turns out. Because as easy as it is to say the answer is to move hosts, I personally would like to see the issue truly
solved—with the outcome of MODx being able to run flawlessly in even the least sophisticated ("shabby" in the parlance of the day) of shared hosting environments. According to the email alerts I've received from Pingdom.com these are the times the site has gone blank over the past few days:

So, what the heck am I looking for? Can someone point me in the right direction?
A question for the MODx team regarding web hosts: are the providers listed on the services page at
http://modx.com/services/ reputable and endorsed by MODx? Has the core development team researched these host providers and deemed them worthy and trouble free? Or are these simply a few providers that have chosen to advertise here? One might deduce that if these particular providers were willing to spend a few bucks to advertise to us MODxers, then they also must support MODx as well. I am not opposed to moving hosts, and will most certainly recommend whatever hosting will work best for future projects.

Well, I could come up with more reasons why you need to move from GoDaddy, but the fact that you are being obstructed in researching a problem because there are no server error logs available is a pretty big one. While you say you have other sites working just fine, that doesn't make GoDaddy a good host and there's likely something different about this one. Maybe more traffic, more search engines hitting it or it simply is a heavier website that requires more resources than other sites you run there.
